Client connectivity has been implemented and is now operational. Optiq®, Euronext’s proprietary state of-the-art technology, has also been successfully installed in Bergamo. The colocation and connectivity offerings have been designed and shared with clients. As a next step, Euronext is working on the client installation (equipment shipping, installation, and testing), which is set to be finalised in June 2022. 2022 Costs Guidance To highlight its underlying performance, from Q1 2022 Euronext will adjust its operating expenses and publish an adjusted EBITDA excluding non-recurring items, such as implementation costs related to the Borsa Italiana Group integration.
